all my clones have rusty leaves and other problems...

ive got 6 clones that were growing fine all along and
then yesterday i noticed that MANY leaves on all plants
are turning rusty and spotty... some are drying up and
dying... i pinched off some of the worst ones, but they
seem to be spreading UP the plants and the plants are
now growing very slowly and the growth is weak and thin...

i use foxfarm growbig just as i always have... nothing has
changed outside of it getting a little colder, could that have
anything to do with it?

i dont want to lose all my babies... any ideas?

picture please..
Have they rooted?
Doesn't sound like they are "clones"

Sounds like they are plants.

Manganese (Mn) immobile would be my guess.

Red & brown spots on the tops of the leaves and maybe a red streak on the stem or stock as well?

What is the humidity around your plants?

Try making a foil spray with about 5% Epsom salt and give them a good soak when the lights are on. Add some Epsom salt to your water too about 5-ml per gallon works.

If you do have a dry environment that will cause additional transpiration and in turn cause more manganese to be drawn into the foliage.

That's just a guess from what you are saying.

Will this epson salt work for the hydro? donnie

Sure you just mix it up is all the salt will dissolve quickly.
